我正在开发一个应用程序，用于索引嵌入式Derby（10.12.1.1）数据库中的一堆文件，然后导出为一个单一的列表文件。第一部分工作正常，因为创建了DB并且索引了所有记录。
但是，当我尝试使用JdbcPagingItemReader从数据库读取并写入文件时，我只获得pageSize中指定的记录数。因此，如果pageSize为10，那么我得到一个包含10行的文件，其余的记录似乎被忽略了。到目前为止，我还没有找到真正发生的事情，任何帮助都会受到欢迎。
以下是JdbcPagingItemReader配置：

</batch:step>
</batch:job>
修改
根据Hansjoerg Wingeier的建议，我将步骤6中的commit-interval与pageSize配置中的JdbcPagingItemReader进行了匹配。另外，我扩展了JdbcPagingItemReader只是为了记录调用 doReadPage 方法的次数。事实证明，它只调用了两次，但 rowmapper 只能从第一页获取项目。
此外，我尝试使用 JdbcCursorItemReader ，但它抛出了一个SQL异常，上面写着'getRow（）'方法只允许滚动游标。
这是 JdbcCursorItemReader congig：

答案 0 :(得分：0)
根据Hansjoerg Wingeier的建议，我决定使用JdbcCursorItemReader并通过设置 verifyCursorPosition = false 来解决 UncategorizedSQLException ，如here所述。
这是 JdbcCursorItemReader 的最终配置：
